##Using Let's Encrypt certificates with AWS API Gateway

Before starting off with API Gateway set up it's worth mentioning that certificate configuration for this particular service is so far isn't well integrated, therefore different from other AWS services. Despite it using CloudFrount to serve on custom domains it won't let you customize distributions it creates, however all the limitations of CloudFront naturally apply to API Gateway. The most important in this case is the size of the key, which is limited by 2048 bit. Many tutorials provide ready to use terminal commands that have the key size preset at 4096 bit for the sake of better security. This won't work with API Gateway and you'll get an error message about certificate's validity or incorrect chain which won't suggest you the real cause of the issue. Another consideration is that to add a custom domain to API Gateway you have to have a certif

A quick overview of the node.js streams interface with basic examples.

This is based on @brycebaril's presentation, Node.js Streams2 Demystified

Overview

Streams are a first-class construct in Node.js for handling data.

Think of them as as lazy evaluation applied to data.

Clustering: The basics

The trick? pass the file descriptor from a parent process and have the server.listen reuse that descriptor. So multiprocess in their own memory space (but with ENV shared usually)

It does not balance, it leaves it to the kernel.

In the last nodejs > 0.8 there is a cluster module (functional although marked experimental)

• http://nodejs.org/api/cluster.html
• Simple cluster example:

getify

// NOTE: only escapes a " if it's not already escaped
function escapeDoubleQuotes(str) {
	return str.replace(/\\([\s\S])|(")/g,"\\$1$2"); // thanks @slevithan!
}

escapeDoubleQuotes(`ab`);          // ab  =>  ab           (nothing escaped)
escapeDoubleQuotes(`a"b`);         // a"b  =>  a\"b
escapeDoubleQuotes(`a\\"b`);       // a\"b  =>  a\"b       (nothing escaped)
escapeDoubleQuotes(`a\\\\"b`);     // a\\"b  =>  a\\\"b
escapeDoubleQuotes(`a\\\\\\"b`);   // a\\\"b  =>  a\\\"b   (nothing escaped)
